D. Optional Air Line Filter Installation
Filtering is required when using air from a compressor to
insure that moisture and debris from the supply hose does
not enter the torch. Although the unit is standard with
the Two Stage Air Filter there is an Optional Single-Stage
Filter Assembly that may be used. Install the Optional
Single-Stage Filter as follows:
1. Remove the air hose connected between the Two
Stage Air Filter OUT port and the Regulator/Fil-
ter Assembly.
2. Connect the gas supply as shown. Typical fittings
are shown as examples. Other fittings can be used.

E. Using High Pressure Gas Cylinders
Refer to the following when using high pressure gas cylinders
as the gas supply:
CAUTION
Pressure should be set at 100 psi (6.9 bar) at the
high pressure gas cylinder regulator.
• Refer to the manufacturer’s specifications for
installation and maintenance procedures for
high pressure gas regulators.
• Examine the cylinder valves to be sure they
are clean and free of oil, grease or any foreign
material. Momentarily open each cylinder
valve to blow out any dust which may be
present.
• The cylinder must be equipped with an ad-
justable high-pressure regulator capable of
outlet pressures up to 100 psi (6.9 bar) maxi-
mum and flows of up to 300 scfh (141.5 lpm).
1. Remove the air hose connected between the Two
Stage Air Filter OUT port and the Regulator/Fil-
ter Assembly.
NOTE
Supply hose must be at least #4 hose (1/4 in or 6
